Use user input in a function

I want to use a user input variable in a function

like:

n=input('n')
k=3
f1=func(k)
function f1=func(x);
f1=n*x;
end

But when I write that code it gives me this message:

Unrecognized function or variable 'n'.

Error in untitled>func (line 5)

f=n*x;

How can I do this?

[kei hin]

k=3
f1=func(k)
function f1=func(x);
n=input('n')
f1=n*x;
end

or

n=input('n')
k=3
f1=func(n,k)
function f1=func(n,x);
f1=n*x;
end
